Description

Technical Field

[0001] This utility model belongs to the technical field of phase shifter welding fixtures, specifically relating to an automated welding fixture for phase shifter components. Background Technology

[0002] Phase shifter assemblies play a crucial role in communications and radar. Phase shifters alter the phase of signals, enabling precise control of the signal beam, thereby improving key performance indicators such as communication capacity, coverage, radar resolution, and detection range. A phase shifter assembly typically consists of a tray, PCB, slider assembly, and coaxial cable; the quality of the connections between these components directly affects the overall performance of the phase shifter.

[0003] Traditional phase shifter assembly manufacturing primarily relies on manual operation. This involves manually securing the PCB to a tray, fixing the slider to the PCB, and finally placing the cables for soldering. This manual process is relatively slow, severely limiting production efficiency and product quality. To improve efficiency, welding equipment with appropriate fixtures is used for automated welding. However, existing welding fixtures have simple structures, allowing only one phase shifter assembly to be welded at a time, failing to fully utilize the advantages of automated welding equipment. Furthermore, the cable securing methods are cumbersome, requiring significant time and effort, further reducing welding efficiency. Utility Model Content

[0004] (1) Technical problems to be solved In view of the shortcomings of the existing technology, the purpose of this utility model is to provide an automated welding fixture for phase shifter components. This fixture aims to solve the problems that the existing welding fixtures for phase shifter components cannot fully utilize the advantages of automated welding equipment, and that the cable fixing method is cumbersome, which reduces welding efficiency.

[0005] (2) Technical solution To solve the above-mentioned technical problems, this utility model provides an automated welding fixture for phase shifter components. The fixture includes a tray and a pressure plate. The tray has at least two phase shifter placement slots. Multiple cable slots penetrating the tray are provided on the front and rear sides of the phase shifter placement slots. An elongated hole penetrating the upper and lower sides of the tray is provided in the middle of the phase shifter placement slot. The length of the elongated hole is greater than the width of the phase shifter placement slot, and the elongated hole is inclined. The ends of the two elongated holes on the left and right sides overlap and are staggered. The pressure plate is magnetically fixed to the tray.

[0006] Preferably, a phase shifter assembly is placed in the phase shifter placement slot. The phase shifter assembly includes a phase shifter body, a phase shifter bracket, a slider, and a cable. The elongated hole is larger than the size of the slider, and the cable is located in the cable groove.

[0007] Furthermore, the front and rear sides of the bottom wall of the phase shifter placement slot are provided with clearance openings corresponding to the phase shifter bracket, and the clearance openings penetrate the lower surface of the tray.

[0008] Furthermore, multiple clearance holes are provided on both the front and rear sides of the bottom wall of the phase shifter placement slot, and the clearance holes penetrate the lower surface of the tray.

[0009] Furthermore, the pressure plate includes a first pressure plate and a second pressure plate, which are used to press the cable in the cable groove.

[0010] Furthermore, a first magnet block is fixedly connected to both the left and right sides of the cable channel on the tray, and a second magnet block corresponding to the first magnet block is fixedly connected to the lower surface of both the first pressure plate and the second pressure plate.

[0011] Furthermore, both sides of the lower surface of the tray are fixedly connected with shims.

[0012] (3) Beneficial effects Compared with the prior art, the beneficial effects of this utility model are as follows: 1. This utility model has at least two phase shifter placement slots on the tray. During welding, the phase shifter assembly is placed in the phase shifter placement slot. At this time, the slider is located in the elongated hole. Since the elongated hole is larger than the size of the slider, the maximum travel of the slider is cleared to allow the slider to be smoothly placed into the tooling for operation at any angle without positioning or adjustment. Furthermore, magnetic fixation is used to fix the pressure plate to the cable, thereby simplifying the operation process and welding at least two phase shifter assemblies at a time, thus improving production efficiency. 2. This utility model effectively utilizes the space of the tray by staggering the long holes in the middle of the two phase shifter placement slots and adopting a staggered inlay layout structure. It can load at least two sets of phase shifter components in a limited space, thereby reducing the tooling area, reducing the tooling manufacturing cost, and improving the adaptability to general automatic welding machines, thus improving the efficiency of automated welding.

[0020] This specific embodiment is an automated welding fixture for phase shifter components, and its structural schematic diagram is shown below. Figures 1-6 As shown, the tooling includes a tray 1 and a pressure plate 2. The tray 1 has at least two phase shifter placement slots 3. Multiple cable slots 4 are provided on the front and rear sides of the phase shifter placement slots 3, passing through the tray 1. The middle of the phase shifter placement slots 3 has an elongated hole 5 that passes through the upper and lower sides of the tray 1. The length of the elongated hole 5 is greater than the width of the phase shifter placement slots 3, and the elongated hole 5 is inclined. The ends of the two elongated holes 5 that are close to each other overlap and are staggered. The pressure plate 2 is magnetically fixed to the tray 1.

[0021] like Figure 1 , Figure 3 and Figure 6 As shown: In this embodiment, a phase shifter assembly 6 is placed in the phase shifter placement slot 3. The phase shifter assembly 6 includes a phase shifter body 601, a phase shifter bracket 602, a slider 603 and a cable. The elongated hole 5 is larger than the slider 603 and has rounded ends. The cable is located in the cable groove 4.

[0022] During welding, the phase shifter assembly 6 is placed in the phase shifter placement slot 3. At this time, the slider 603 is located in the elongated hole 5. Since the elongated hole 5 is larger than the size of the slider 603, the size of the elongated hole 5 is designed to allow for clearance based on the maximum travel of the slider 603, so that the slider 603 can be smoothly placed into the fixture at any angle for operation without the need for positioning or adjustment.

[0023] To reduce the thickness of tray 1, such as Figure 3 , Figure 4 and Figure 6As shown: In this embodiment, the front and rear sides of the bottom wall of the phase shifter placement slot 3 are provided with clearance openings 301 corresponding to the phase shifter bracket 602. The clearance openings 301 penetrate the lower surface of the tray 1. The front and rear sides of the bottom wall of the phase shifter placement slot 3 are provided with multiple clearance holes 302. The clearance holes 302 penetrate the lower surface of the tray 1. When the phase shifter assembly 6 is placed into the phase shifter placement slot 3, the phase shifter bracket 602 passes through the clearance openings 301, the slider 603 is located in the elongated hole 5, and the multiple clearance holes 302 avoid the protruding part connected to the phase shifter assembly 6.

[0024] To facilitate the fixing of the welded cables, such as Figure 1 , Figure 2 and Figure 5 As shown: In this embodiment, the pressure plate 2 includes a first pressure plate 201 and a second pressure plate 202. The first pressure plate 201 and the second pressure plate 202 are used to press the cable in the cable groove 4. Two first magnet blocks 7 are fixedly connected to the tray 1 on both the left and right sides of the cable groove 4. The lower surfaces of the first pressure plate 201 and the second pressure plate 202 are fixedly connected to second magnet blocks 8 corresponding to the first magnet blocks 7. By installing the pressure plate 2 on the tray 1, the first magnet blocks 7 and the second magnet blocks 8 are magnetically attracted together, thereby pressing the first pressure plate 201 and the second pressure plate 202 onto the cable for fixation, thus simplifying the fixing process and making it very convenient.

[0025] To better assemble pallet 1 into the automated welding fixture, such as Figure 1 As shown: In this embodiment, both sides of the lower surface of the tray 1 are fixedly connected with shims 9. The height of the shims 9 is greater than the height of the phase shifter bracket 602 extending out of the tray 1. The shims 9 not only raise the tray 1 to prevent the phase shifter bracket 602 from contacting the equipment, but also make it more stable to place.

[0026] Working principle: First, assemble the phase shifter body 601, phase shifter bracket 602, and slider 603. Then, place the phase shifter assembly 6 into the phase shifter placement slot 3. At this time, the phase shifter bracket 602 passes through the clearance opening 301, and the slider 603 is located in the elongated hole 5. Then, install the cable in the cable groove 4 according to the required cable length. At this time, the other end of the cable is located at the welding position of the phase shifter assembly 6. Next, install the pressure plate 2 on top of the tray 1. Due to the use of magnetic fixation, the cable fixing is more convenient. Finally, assemble and fix the phase shifter assembly 6. The tray 1 fixture is placed in the automated equipment. The automated equipment is started, and a dual-axis soldering iron device is used to automatically solder the wire cores, braids, and other solder joints of the cable on the phase shifter assembly 6. After the soldering is completed, the phase shifter assembly 6 is taken out and placed as required. The advantage of this fixture is that for automated equipment with a single welding fixture, the fixture can be changed for operation. For automated welding equipment with a double welding fixture, while the automated equipment is working at one end, the assembly of the phase shifter assembly 6 and the cable can be performed manually at the other end, achieving the goal of human-machine balance and maximizing efficiency.

[0027] All technical features in this embodiment can be freely combined according to actual needs.

[0028] The above embodiments are preferred implementations of this utility model. In addition, this utility model can also be implemented in other ways. Any obvious substitutions without departing from the concept of this technical solution are within the protection scope of this utility model.
